' RECORDING MECHANISM.

Specification of Letters Patent? Patented Aug. 22, 1916.

Application filed August 13, 1912. Serial No. 714,822.-

. a citizen of the United States, residing at Detroit, in the county of Wayne-and State of Michigan, have invented certain new and useful Improvements in Recording Mechanisms, of which the following is a specification.

The vpresent invention relates to recording mechanisms for adding machines which rovide for separately listing items upon independent strips or sheets of paper, and

may be regarded as an improvement upon the invention of Jesse G. Vincent, disclosed in Patent No. 968,005, issued August 23rd, 1910, to Burroughs Adding Machine Company. In that Vincent patent a laterally shiftable paper carriage is shown carrying two roller platens axially alined but independently rotatable, having separate linespacing mechanisms. \Vhile it would be possible to'actuate both line-s acing mechanisms of that Vincent machine simultaneously and so turn the two platens as one, the Vincent arrangement was not designedwith thatend in view, and so included no special equipment for converting the machine at will from a single platen to a duplex platen condition. 1

One object of the present invention is to provide for employing the platen structure in sections or as a single platen, at the will of the user of the machine, to which end, in the constructionhere shown, the sections of the roller platen are closely assembled and a coupling is provided for uniting them rotatably.

Another object of the present invention is to prevent the possibility of any mis-opnation or locking-up of the parts by reason of the shifting of the carriage while an operation of the machine proper is in progress. To this end, in the construction here shown, a lockin device is provided for engaging the carriage during the operation of themachine proper whenever the carriage occupies a position Where the inner end portion of either of two line-spacing bail-rods is embraced by the jaws of the line-s acing slide, which is reciprocated by an e ement of the machine proper in the customary manner. I v T I \Vith the above stated objects in view, the invention consists in certain novel features of constructionand combinations of parts,

the essentials of which are recited in the rap ended claims, and a referred form of emodiment is illustrate in the accompanying drawings, described in detail hereinafter.

Of said drawings Figure 1 represents in rear elevation partly broken away an adding machine equipped with mechanism embodying my invention; Fig. 2 is a sec} from that illustrated in Fig. 1; Fig. A: is a sectionalized top plan view .of the platen structure; Fig. 5 is a horizontal section on a lower plane; Figs. 6 and- 7 are detail perspective views.

I have not considered it essential to illustrate or describe the adding machine proper, since the present invention is not concerned with adding functions. state that the invention'is here shown adapted to the well-known Burroughs type of adding and listing machine and the paper carriage equipment is of the same character in the main as used upon this machine and as disclosed in a number of rior patents, including that to Vincent, a ready identi fied. It willtherefore sufiice to briefly mention familiar elements of the carriage equipment, such as the main carriage frame 17 slidably mounted at the back of the machine;

and the cradle 17, carried at the upper part of said main frame; also the rock rod G at the lower part of the carriage frame, carrying a series of tabulator fingers H for determining various columnar positions of the carriage through engagement with a notched plate mounted uponthe back panel 2 of the machine proper.

The sections of the roller platen are designated respectively A and B, the latter pre erably of such length as to accommodate a wide sheet of paper, while the section A is shorter and adapted for receivingthe usual paper strip drawn from a roll. These laten sections are axially alined in thecrad e 17',

but capable of turning independently of each other. As the purpose is to use both platen sections together when the work in hand calls for a single platen condition, the inner heads a and b, Fig. 4,'are brought 'close together so that the surfaces of the laten sections may be virtually continuous. urthermore, in the interests of securing However, 'I may as one.

perfect alinement under such a condition, the spindles or shafts of the platen sections are telescoped, thus the spindle or shaft A, to which the platen section A is secured, has a somewhat elongated inner end portion a of reduced diameter, which engages a bore of the spindle or shaft B to which the section B is secured. Preferably the said reduced portion of the shaft .or spindle A is further reduced in diameter throughout the greater part of its length, as illustrated in Fig. 4, in order to minimize the surface machined for engaging the bore of the spindle B.

For the purpose of coupling and uncoupling the platen sections a pin or bolt W is mounted to slide in the heads of the platen section A and project into an aperture or socket b in the head I) of the platen section B. A coiled spring '10 surroundin the pin or bolt between the outer head 0 the platen section A and a collar 40 secured to said pin orzbolt, exerts itself to enforce engagement of the pin orbolt with the aperture or socket b of the head I) of the platen section 13. Preferably this bolt or pin slides through a bushing to which is screwed into a tapped opening in the outer head a of the platen section A, which arrangement facilitates assembling, since the pin or bolt with its collar 'w and spring w can be put in place together with the said bushing 10 It will of course be obvious that when the pin or bolt is engaged with the platen section B, as shown in Fig. 4, the two platen sections are rotatably connected so as to turn This connection can be broken at will or the platen sections uncoupled by simply drawing out the bolt or pin. The latter has a head wflto bear against the bushing '21; and said head is'fianged as shown at wto facilitate taking hold of it to draw out the pin or bolt. In order to provide for maintaining the bolt in uncoupling position it is equipped with a stud w, Fig. 6, which normally seats in a radial groove w in the outer end of the bushing (Fig. 7). The bolt is rotatable, so that when drawn out the said stud may be turned over a plain part of the bushing so as to prevent reengagement of the bolt with the platen section B.

Each platen section has its own line-spacing equipment comprising ratchetwheel A (B pawl A (B pawl carrying arms A (13*), link A (B and notched and slotted lates A'-(B). As shown in the aforesaid incent patent, the notched and slotted plates are secured respectively to rock shafts A 7 journaled in the paper carriage and forming parts of two bails comprising respectively cross-rods A -B which are normally in alinement as illustrated in Fig. 5. The construction here shown further corresponds with that illustrated in the Vincent patent inthat either of said cross rods is adapted to be engaged by the jaws 18 of masses the reciprocating plate 18, mounted as usual upon the back panel 2 and reciprocated by the lever 18*, which is vibrated by the cam 18 secured to the machine shaft 100, Fig. 2. In order to avoid the possibility of either bail cross-rod engaging over the top of said jaws, as a result of the shifting of the carriage during operation. of the machine when the jaws are engaged with the other rod near the inner end thereof, I provide a lock to prevent shifting of the carriage during the operation. Thus there is pivoted to the back panel 2, Figs. 1 and 3, a short lever X having at its extremity on one side of its pivot a laterally turned portion :12 adapted to engage either one of two notches 17 b and 17 formed in the under side of the main carriage frame 17. A spring or applied to said lever on the other side of its pivot enforces engagement of the laterally turned portion or car m with said notches under the condi tions presentl to be mentioned. The reciprocating slide 18 is formed with a laterally projecting lug 18 which engages the arm of the lever X, to which the spring at is applied, and normally stretches that spring as shown in Fig. 1 and holds the lever X in a position where its ear w is outof engagement with the carriage altogether. It is only when the carriage adjustment is such as to bring the inner portion of one bail cross-rod or the other into engagement with the jaws 18 that there is danger of a lockup, due to shifting of the carriage when the bail rod is depressed by the slide 18, the other bail rod not being affected and so in a position to pass over the top of the jaws under a shifting of the carriage. Therefore I find it necessary only to employ the two notches 17 b and 17 located to correspond with the two positions of the carriage, in one of which the bail rod A has its inner portion engaged with the jaws 18*,as shown in Fig. 3, and in the other of which the inner or adjacent portion of theother bail rod B will be engaged with said jaws. Fig. 3 illustrates the, action of the latch lever X under the conditions in question. riage is in a-position where the inner portion of the bail rod A is engaged by the jaws l-8 and the slide 18 is represented in its lowered position. With the lowering of that slide its lug-18 releases the lever X so that the latter immediately becomes engaged with the notch 17 "The square side of this notch is tothe left as the machine is viewed fromthe rear and consequently so long as the where the inner portion of the bail rod 13 is engaged with the jaws 18 depression of the plate 18 will result in the lock lever X en- Here the cargaging the other notch 17 ,the square side of which is to the right as the parts are viewed from the rear and hence prevents further movement of the carriage to the left or in a direction to slide the bail rod B out from between the jaws 18 and the bail rod A? over said jaws. Of-course with the com- )letion of the operation in either case the iug 18 will act upon the lever X and unlock the carriage.
